What does MIVEC stand for?
MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) is the brand name of a variable valve timing (VVT) engine technology developed by Mitsubishi Motors.
What is operation Operation in MIVEC?
Operation. MIVEC switches to the higher cam profile as engine speed increases, and drops back to the lower cam profile as engine speed decreases. The reduced valve overlap in low-speed mode provides stable idling, while accelerated timing of the intake valve’s closing reduces backflow to improve volumetric efficiency,…
When did the Mitsubishi 4G92 come out with MIVEC?
MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1,597 cc naturally aspirated DOHC 16 valve straight-4. At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control.
When did the Mitsubishi Mirage first use MIVEC?
MIVEC was first introduced in 1992 in their 4G92 powerplant, a 1,597 cc naturally aspirated DOHC 16 valve straight-4. At the time, the first generation of the system was named Mitsubishi Innovative Valve timing and lift Electronic Control. The first cars to use this were the Mitsubishi Mirage hatchback and the Mitsubishi Lancer sedan.
Mitsubishi Innovate Valve Timing Electronic Control System
MIVEC is a type of VVT engine technology developed by Mitsubishi Motors and it is used on all Mitsubishi engines. The acronym stands for “Mitsubishi Innovate Valve Timing Electronic Control System.” But before you can understand MIVEC, you need to know about VVT.
Is MIVEC and VTEC the same?
VTEC and mivec are just systems that enable a car to use 2 cam profiles on the same shaft. Nothing more.
What is Mitsubishi CVT?
The continuously variable transmission, involves a system that uses two cones connected by a belt and choses the ideal ratio between its pulleys to optimize engine torque. This transmission is designed lighter and more compact than a automatic or manual transmission. It is also long-term sustainable.
What is Mivec CK?
MIVEC (Mitsubishi Innovative Valve timing Electronic Control system) is the brand name of a variable valve timing (VVT) engine technology developed by Mitsubishi Motors. The first cars to use this were the Mitsubishi Mirage hatchback and the Mitsubishi Lancer sedan.
Is Mivec a CVT?
From the 4B1 engine family onward, MIVEC has evolved into a continuous variable valve timing (CVVT) system (dual VVT on intake and exhaust valves).
What is the difference between the Silvertop and the Blacktop?
However the method used varies between engines as the Silvertop uses a simple Vane type airflow meter whilst the Blacktop uses a more complex vacuum (MAP) and throttle position (TPS) for larger throttle openings where there is no vacuum. The Blacktop engine featured no airflow meter as such but did have an additional vacuum sensor (MAP sensor).
Are a blacktop and silvertop Pistons interchangeable?
A Blacktop engine is an interference engine unlike all other A series engines. Although the pistons are initially interchangeable physically they aren’t practically as a Silvertop with Blacktop pistons has a very high compression and quite low when the combination is reversed.
What is the difference between the silvertop velocity stacks and Blacktop trumpets?
The Silvertop Velocity stacks / trumpets are formed out of a hard plastic while the Blacktop uses a firm rubber instead for their construction. They aren’t readily interchangeable because the two mounting bolts are further apart on the Blacktop trumpets. Please see “Throttle bodies” for more information.
How much horsepower does a MIVEC engine have?
At high speeds, the MIVEC system switched to large cams, their duration is 283/300 deg, and the lift is 10.41/9.83 mm. The power of this engine reached 170 HP at 7,500 rpm, the torque was 167 Nm at 7,000 rpm. – 4G92 MIVEC Silvertop with the rev limiter at 7,800 rpm.
